> do these corrections

ad infinitum

In that case....

"wrong" and "right" are adjectives, while "writing" is a verb which you are using the words "wrong" and "right" to modify. However, adjectives should only be used to modify nouns and pronouns, not verbs. In this case you should use an adverb:

why get used to writing stuff incorrectly, when I can get used to writing them correctly

If you prefer, you can use "writing" as a noun and continue to use "right" and "wrong":

why get used to the wrong way of writing when I can get used to the right way

I hate people who correct grammar on the internet, but you did make the mistake of asking. Sorry.

Please, no. I avoid taking part in grammar threads, but a plea for more has drawn me out. There are few things that derail conversations more than pedantic quibbling about "do" or "make". Take a look at this subthread: a bunch of people who feel better about how they've shown themselves able to one-up others but zero interesting discussion.

My biggest feature request for HN: private comments. Let me reply to a poster privately. Then if I see somebody who looks like a non-English speaker who has made a mistake or somebody who has misspelled a name, I can correct them without causing this kind of useless thread. Not to mention private conversations (where you could say more than you are willing to say publicly) started around interesting comments could turn epic.
